Normally what happens with the 1.2 timing chain is that the chain tensioner fails and allows the chain to become loose. The chain then is able to jump the teeth on the sprockets for the crank/cams. One or 2 teeth jumping normally causes poor staring and low power from the engine. More teeth jumping can get quite serious in that the electronics will detect that the timing is out and stop you from starting the engine.
In really bad cases the timing can go out enough for the pistons to connect with the valves and bend the valves.
This can cost well in excess of a grand to fix.
good luck chap.
